The buildup most report is the additive separating from the distilled water, or other contaminations... distilled on it's own has nothing to separate down into that can become a buildup etc.

Plain distilled on it's own in a quality loop (no mixedmetals) = less maintenance.

Distilled + Additive = additive needs refreshing every xx months (differs from additive to additive) without fail to maintain anticorrosive properties.
Non-Conductive coolants = collect ions over time becoming conductive unless refreshed every xx months also.
that was informative
thanks
